A couple of drinking buddies, who were airplane mechanics, were in the hanger at Mascot in Sydney. It was fogged in and they had nothing to do. One said to the other, 'Man, have you got anything to drink?' 'Nah, but I hear you can drink jet fuel and that'll kinda give you a buzz.' So, Bill and Bob drank jet fuel, get smashed and had a great time. The following morning, Bill woke up and figured his head would probably start pounding as soon as he stood up. But it didn't. He felt good. In fact, he felt great - no hangover! Bill's phone rang, it was Bob. Bob asked, 'Hey, how do you feel?' 'I feel great!' replied Bill. 'I feel great too! You don't have a hangover?' 'No. That jet fuel is great stuff - no hangover. We ought to do this more often!' 'Yeah, we could, but there's just one thing...' 'What's that?' 'Did you fart yet?' 'What?' 'Did you fart yet?' 'No...' 'Well, don't, because I'm in Melbourne!'
